Answer:

The magnetic field line data refutes the claim that the magnets were misaligned in the Tuesday launch.

Explanation: The data shows that there was no difference in the pattern of the field lines for all three launches. If the magnets in Tuesday's test had been misaligned, the force between the magnets in that test would be different than in the other test, showing both attraction and repulsion. During a misalignment at least one field line would connect opposite poles of the other magnets, but the magnetic field lines data we received did not show proof of misalignment.  Therefore the magnets were correctly aligned on Tuesday.

Answer:

Similarity: Rocks within the mantle contain more magnesium and iron than the ones in the crust.

Difference: Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly. On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.

Explanation:

Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly.

On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.

According to geologists, a rock is a naturally occurring material made up of crystalline crystals of various minerals that have fused together to form a solid mass.

Therefore, Rocks within the mantle contain more magnesium and iron than the ones in the crust.

b)

1 : 2 : 2 (I don't know if this is what the question wants but it is what I would answer)

c)

Hydrogen because it requires 2 moles of H2 to react with 1 mole of O2

d)

24 moles of water. Look at stoichiometric coefficient. 2:2 means 24 moles you get 24 moles

e)

Oxygen. 2 < 5/2. Remember, 1 mole of O2 requires 2 moles of H2. But 5/2 is still greater than 2

f)

First, let's find out how many moles of water we can get. Since O2 is the limiting reactant, and O2:H2O ratio is 1:2, we will get 4 moles of H2O. Then, we can multiply 4 by Avogadro's number which is [tex]6.022*10^{23}[/tex] to get the number of molecules. We get: 2.41 * 10^24 molecules of water.

Answer: aluminium, mercury , platinum and copper.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

[tex]XY+Z\rightarrow XZ+Y[/tex]

Thus the metals which are more reactive than magnesium will react with magnesium sulphate solution.

The metals which are more reactive than magnesium are aluminium, mercury , platinum and copper.

Answer:

0.045 moles

Explanation:

Given data:

Moles of CO = ?

Volume of gas = 1 L

Temperature and pressure = standard

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

n = PV/RT

n = 1 atm× 1L / 0.0821 atm.L/mol.K × 273 K

n = 1 atm.L / 22.41 atm.L/mol

n = 0.045 mol

Type of reaction: Displacement Reaction

The provided word equation depicts a chemical reaction between magnesium and zinc oxide that results in the creation of magnesium oxide and zinc.

Magnesium and zinc oxide are the reactants in the process. These are the substances that alter chemically. The process produces magnesium oxide and zinc. These are the new chemicals produced by the chemical process. This reaction undergoes a chemical transformation, as indicated by the term equation. Magnesium oxide and zinc are formed when magnesium interacts with zinc oxide.

The reaction's stoichiometry is not explicitly stated in the word equation. We cannot establish the exact quantities of the reactants and products involved without further information or factors. The term equation denotes that the reaction obeys the rule of mass conservation. The total mass of reactants must equal the total mass of products.

Explanation:

Answer:

19

Explanation:

The mass of an atom is given by its mass number. This is because the mass of an atom is concentrated at the nucleus.

Mass number = number of protons + number of neutrons

Protons and neutrons are the most massive particles in any atom.

Protons are the positively charged particles in an atom

Neutrons are uncharged particles.

  So, the mass number of this atom is:

      Mass number  = 9 + 10 = 19

Answer:

[tex]T_1 = -57.15^{\circ}C[/tex]

Explanation:

Given

[tex]P_1 = 650mmHg[/tex] --- Initial Pressure

[tex]V_1 = 5.0L[/tex] --- Initial Volume

[tex]V_2 = 5.7L[/tex] --- Final Volume

[tex]P_2 = 800mmHg[/tex] --- Final Pressure

[tex]T_2 = 30C[/tex] ---- Final Temperature

Required

Determine the initial temperature (T1)

This question will be solved using combined gas law which states:

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

However, the final temperature must be converted to degree kelvin

[tex]T_2 = 30C[/tex] --- Add 273.15

[tex]T_2 = 30k + 273.15 k[/tex]

[tex]T_2 = 303.15k[/tex]

Make T1 the subject in [tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

[tex]T_1 = \frac{P_1V_1T_2}{P_2V_2}[/tex]

Substitute values for P1, V1, T2, P2 and V2

[tex]T_1 = \frac{650 * 5.0 * 303.15}{800 * 5.7}[/tex]

[tex]T_1 = \frac{985237.5}{4560}[/tex]

[tex]T_1 = 216.060855263[/tex]

Approximate

[tex]T_1 = 216k[/tex]

Convert to degree Celsius

[tex]T_1 = 216k[/tex] --- Subtract 273.15

[tex]T_1 = 216 - 273.15[/tex]

[tex]T_1 = -57.15^{\circ}C[/tex]

Hence, the initial temperature is -57.15C

Advantage and disadvantage of asexual reproduction in plant is described below in details.

Explanation:

An advantage of asexual reproduction is that the resulting plant will approach adulthood quicker. Since the new plant is emerging from a grown-up plant or plant components, it will also be stronger than a seed. Asexual reproduction can take a spot by natural or manufactured (assisted by humans) means.

The significant disadvantages of asexual reproduction are the Shortage of diversity. Following the seeds are genetically the same as the parent they are more sensitive to the same diseases and nutrient insufficiencies as the parent. All the negative deviations endure for generations.

Answer:

Magma becomes rock after the heating process has settled.

Explanation:

Magma is a kind of lava or in other words "Hot melted rock". When rock get really hot it transforms from rock it's solidified state and becomes magma. When magma is hot it can stay that way for a while or until it cools down. When magma does cool down it starts the solidifying state start to come out. If you let the magma cool it will become rock again. This process will happen over and over and it never stops. Every time magma gets cool it hardens, every time it gets hot it melts or and becomes magma. So in conclusion magma only turns back when it has been heated up and liquify.

The rock cycle explains the formation and breaking of the three forms of the rocks through various modes. The magma becomes rocks and magma again through the heating and cooling process.

Magma has been the semi-hot liquid that is present in the mantle in the lithosphere of the earth. They have very high temperatures and can push through the crust in the form of volcanic eruptions.

The magma changes its form from semi-liquid to rocks and back to magma again through the rock cycle. The hot molten magma pushes through the crust, cools, and then forms rocks. These rocks after many years start melting at higher temperature or get deep down the mantle where it converts to semi-liquid again.

Therefore, the rock cycle converts the magma.

Answer:

Molecular formula = C₄H₁₂O₂

Explanation:

Given data:

Percentage of hydrogen = 13.80%

Percentage of carbon = 51.02%

Percentage of oxygen = 35.18%

Molecular formula = ?

Solution:

Number of gram atoms of H = 13.80 / 1.01 = 13.6

Number of gram atoms of O = 35.18 / 16 = 2.2

Number of gram atoms of C = 51.02 / 12 = 4.25

Atomic ratio:

            C                      :      H             :         O

           4.25/2.2           :     13.6/2.2     :       2.2/2.2

            2                      :        6          :        1

C : H : O = 2 : 6 : 1

Empirical formula is C₂H₆O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = C₂H₆O = 46 g/mol

n = 88 / 46

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₂H₆O)

Molecular formula = C₄H₁₂O₂
